The results of a detailed chemical model of the transient stratospheric chemistry following passage of a large solid rocket booster motor is described. The model is based on SURFACE CHEMKIN, which is a newly developed multiphase chemical kinetic model. The model incorporates 34 chemical species and over 100 gas phase, heterogeneous, and photochemical reactions. The results show that passage of a Titan IV-sized rocket should produce an ozone 'hole' 10 km in diameter at 20 km altitude, and 28 km in diameter at 30 km altitude, lasting from a few hours to a day. The size and persistence of the hole are very sensitive to the rate of dissipation of the rocket plume, which is poorly understood at present.
